3VT switch disconnectors can be used as the main switch for sub-distribution boards, repair and transfer switches for cables, busbars or device combinations.

As three and four-pole versions, they ensure activation and deactivation of the specified rated current under load. At the same time, they constitute a safety isolating function and isolating distance in all low-voltage circuits.

The position of the toggle levers reliably corresponds with that of the contacts (positive operation).

All 3VT switch disconnectors meet the requirements of IEC 60947-1 and IEC 60947-3.
